If you’ve been anywhere near TikTok or Instagram over the last few years, you’ll know the 40oz Stanley Quencher is the cup to have. I resisted for a while because we have so many Yeti tumblers (if you saw my reel, you probably know that already, and that’s not even our whole collection!) but I really wanted a big cup with a straw. So I ended up with both: a 40oz Stanley Quencher and Yeti’s 35oz Rambler Straw Mug, which is what most people mean when they search for a “Yeti Quencher”.
The quick answer
Get the Stanley if you want the bigger capacity, the longest official ice claim (2 days), a lifetime warranty on the cup itself and a lid you can twist shut. Get the Yeti if you want something shorter that’s easier to hold and easier to fit in the dishwasher, or if you already own Yeti Ramblers and like swapping lids between them. In my own ice test they kept pace for the first nine hours, then the Stanley hung on to its ice for longer.
Hang on, is there a Yeti Quencher?
Not officially. “Quencher” is Stanley’s name, so if you’ve searched for a Yeti Quencher, the cup you’re after is the Yeti Rambler Straw Mug. The 35oz is the one I own, and the one I’m comparing here.

How I ended up with both
Since I already had quite a few of the Yeti mugs in various sizes, I asked Yeti if they had or were planning to release a straw cap that could be used with the “stronghold” screw-top range of mugs.
Then, just over a month after I sent that tweet, Yeti tweeted about their new range…
I’m not saying I influenced this, but I’m not not saying it ;) The new Yeti mug was a 35oz one, sitting between the largest 30oz Yeti mug and the 40oz Stanley cup. I only found out about it a while later (considering how much we’ve bought from Yeti and that they send me texts and newsletters about their ranges, I have no idea why it took so long!) and went straight to Dick’s (fnarr) to pick one up.
In the meantime I’d ended up buying one of the 40oz Stanley cups, and found it to be as useful as everyone was saying at getting me to drink more water. It’s such a heavy beast when it’s full though, so I hoped the Yeti would be much more portable. Since they’re so similar, I thought I’d compare the two properly.
Size, weight and the handle
The Stanley is (obviously, with the bigger capacity) taller, at 11in against the Yeti’s 9.8in, and it has a much bigger handle. I found the Yeti much easier to hold, and not just because the Stanley is a heavy beast when it’s full (40oz of water alone weighs about 2.6lb, so yes, picking it up counts as a workout).
I was a little surprised that when empty, my two cups weighed about the same, with only a gram or two between them. (Yeti’s current listings put them further apart, at 1.32lb for the Yeti against 1.18lb for the Stanley, so the newer version with its updated handle may differ from mine.)
Dishwasher
Both are stainless steel and both are officially dishwasher safe. In this situation I prefer the Yeti, because the Stanley is a bit too tall to go in the top rack of my dishwashers! Yeti’s instructions are to put the lid on the top rack and the gasket and straw in the cutlery basket.
Car cup holders
One of the big attractions of the Stanley is that it fits in your car’s cup holder (seriously, if you’ve seen influencers talking about it on Stories, this is one of the first things they’ll mention). Stanley gives the base as 3.1in across, and Yeti says its straw mugs fit any standard cup holder that’s at least 3in wide. Side by side, my Yeti is actually slightly smaller in diameter at the bottom, so if your car has stingy cup holders it’s the safer bet.
Lids, straws and spills
The Stanley’s FlowState lid twists between three positions: a straw hole, a wider opening for drinking without the straw, and a fully closed cover. Stanley describes the closed position as resisting splashes, which is not the same as leakproof.
The nice thing about the Yeti is that the caps are interchangeable with their existing range of Rambler tumblers, so you can easily switch to a hot-drink cap. That’s worth doing, because Yeti says not to use the Straw Lid with hot drinks.
Something I’ve seen people complain about is that neither of these cups is spill proof, and to that I say OF COURSE IT BLOODY WELL ISN’T, THERE’S A HOLE IN THE TOP OF THE LID FOR THE STRAW.
The ice test
One of the claims Stanley makes is that the Quencher will keep drinks iced for 2 days. Yeti doesn’t give a specific time (its page just says “cold even on the hottest days”), but from experience, I know ice lasts a while in one. Of course, I had to test this out.
I put 300g of pebble ice (from our nugget ice maker, because of course we have one) into each cup, put the cap and straw on, and set a stop clock going. Every so often I checked how much ice was left, drained away the meltwater, and recorded it.
Both cups stayed about the same for the first 9 hours, but then the Yeti’s performance went downhill quickly. At 32 hours I knew that would be my final reading because I was about to go to bed and there was very little ice left, and sure enough, when I checked at 38 hours, both cups just had water in.
Not quite the two days claimed, but there are other variables I didn’t account for: the temperature around the cup, the amount of liquid the ice was sitting in (would that have helped the ice last longer?) and the type of ice (we have moulds for giant clear ice cubes, which last ages even in normal glasses, so would they stay solid longer than pebble ice?). This was one test, at home, with one of each cup, so treat it as a real-life indication rather than a lab result. Either way, it’s still a very decent amount of time for a drink to stay cold!
Colours
Both cups come in loads of colours. Yeti has a core range plus seasonal colours that rotate through the year. Stanley is another level entirely: when I first wrote this, I thought it would be fun to make a collage of every 40oz Stanley colour, and soon regretted it because there were nearly 90 of them. That turned into my A to Z guide to every Stanley 40oz Quencher colour, which I’ve kept adding to since. If the colour is half the point for you, start there.
Which one should you buy?
There isn’t one winner, it depends what you’ll use it for.
- For a desk or bedside water cup, the 40oz Stanley. It holds more, it’s what I use on my desk, and the weight matters less if it mostly sits still.
- If you’ll be carrying it around a lot, the 35oz Yeti. It’s shorter and I find it much easier to hold.
- If you already own Yeti Ramblers, the Yeti, so you can mix and match lids.
- If your dishwasher top rack is on the short side, the Yeti.
- If you care most about how long ice lasts, the Stanley, based on both Stanley’s claim and my own test.
- If you want the longer warranty, the Stanley: lifetime on the steel body (lids, seals and straws excluded) against Yeti’s 5 years.
- If you hate spills, neither is leakproof (hole for the straw, remember), though the Stanley’s lid can at least twist shut.
- If you want a particular colour, probably the Stanley, as new ones turn up constantly (see the colour guide).
So which would I buy more of?
Probably the Yeti, since we already have a lot of their other bits so it’s easy to mix and match the tops, and they’re easier to fit in the dishwasher. I’ll keep my Stanley for water on my desk (because it is quite a workout picking it up full!) and I could be tempted to get another for by the bed in the right colour. With how many they put out, it won’t be long until there’s one I love.
Are you Team Stanley, Team Yeti, or a household with far too many cups to have picked a side (hi)?
FAQs
Is there a Yeti Quencher?
No. “Quencher” is Stanley’s product name. Yeti’s equivalent is the Rambler Straw Mug.
Do the Stanley Quencher and Yeti Straw Mug fit in car cup holders?
Both brands say yes. Stanley says the 40oz fits most car cup holders (3.1in base) and Yeti says its straw mugs fit a standard cup holder at least 3in wide.
Are they leakproof?
No. Both have an open straw hole. The Stanley’s lid can twist to a closed position, which Stanley says resists splashes.
Can I use them for hot drinks?
Yeti says not to use the Straw Lid with hot drinks; you’d need to swap to a different Rambler lid. Stanley only quotes cold and iced times for the Quencher.
Which has the better warranty?
Stanley offers a lifetime warranty on its stainless-steel drinkware, excluding lids, seals and straws. Yeti gives 5 years.
Are they dishwasher safe?
Yes, both are. The Stanley is tall, though, so it may not fit your top rack (it doesn’t fit mine).
